Hello,

i'd like to change the voltage regulator in my minoposd in order to power it with 4S directly. Could someone tell me what is the voltage regulator on this board ?
More, is there an existing  schematic ?

Thank you

minoposd is just a firmware that runs on a variety of compatible hardware.  The firmware is maintained by one of the LP developers but the hardware is made by a variety of Chinese manufacturers.  Different ones may use different regulators.  You'd probably also have to change some of the capacitors related to the regulator to a higher voltage rating.

There are a variety of schematics on the web, search for minimosd or minimosd-micro.  The ones you find may or may not exactly match the one you have.

Most people just install a small BEC board to regulate the higher battery voltage down to the required level.
